Soil risk maps – Interpreting soils data for policy makers,agencies and industry

Surface runoff, erosion, compaction and the leaching of potential pollutants from land can degrade the soil resource and damage the water environment, reducing crop yields, causing loss of valuable nutrients and organic matter, together with increasing flood risk. Increasingly, it is recognized that scientific information must be translated into practical tools to change practices and protect the soil and water resource. Working alongside agencies in Scotland, we applied a suite of simple, transparent, rule-based models to identify areas most at risk of exporting sediment and pollutants that may degrade water quality based on field-scale (1:25,000) soil maps. The maps have been used by Scottish Environment Protection Agency, Scottish Water and Scottish Government to assess soil risks to waters from field to regional scale. The work brought scientists together with policy makers, agencies and the water industry to pool their knowledge to apply these practical tools for decision-making. It highlights the need to apply existing knowledge to answer salient questions. All three examples described show that providing the right type of information, which is based on fundamental soils data, can directly influence the implementation of policies, investment and monitoring decisions and provide evidence in support of government. However, this requires both researchers and agency scientists to develop skills as knowledge brokers and to normalize the use of soil data in everyday agency settings.     

基于农牧户视角的荒漠化治理中退牧还草技术综合评价——以内蒙古鄂托克旗为例

农牧户作为退牧还草技术的实施者和重要利益相关者,其对技术的感知度和认可度对于调整和完善退牧还草技术具有重要的现实意义。本文以草地荒漠化典型区域——内蒙古鄂托克旗为例,采用主观层次分析法和客观熵权法相结合的方法,构建包括技术成熟度、技术应用难度、技术相宜性、技术效益和技术推广潜力5个方面的退牧还草技术综合评价指标体系,基于农牧户视角对内蒙古鄂托克旗退牧还草技术进行综合评价。结果表明:1)基于农牧户视角的鄂托克旗退牧还草技术综合评价结果为0.469 8,说明农牧户对于退牧还草技术的综合评价处于中等水平,技术满意度一般,技术可持续性较弱。具体表现为农牧户对于技术自身的草地生态系统退化修复功能持以肯定态度,生态效益评价较高;而对于经济效益和技术可持续性评价较低。2)分项退牧还草技术评价结果由高到低的排序为:技术相宜性、技术效益、技术成熟度、技术应用难度、技术推广潜力。3)分区域研究得出,鄂托克旗退牧还草技术综合评价的区域差异性较小。因此,退牧还草技术的综合评价结果能够反映农牧户对于该项技术的满意程度,为退牧还草技术的持续有效实施提供参考。     

我国生态草牧业政策梳理及评价

草牧业是以草为基础的畜牧业,是在传统畜牧业和草业基础上提升的新型生态草畜产业。我国草原面积近60亿亩,草地畜牧业发展拥有巨大潜力,如何实现草地资源可持续利用是当前政策制定者面临的重要任务与挑战。本研究借鉴柳卸林的政策分析框架,梳理2000年以来我国政府颁布的草牧业政策,并基于呼伦贝尔地区的农、牧户调研,辨识草牧业发展的政策缺口,厘清当地生态草牧业发展中不同利益相关者的需求与困境,为长期的政策制定提供支撑。     

新乡贤队伍建设与乡村振兴:来自绍兴的调查与研究

作为"乡贤研究会"首创之地和"新乡贤"概念诞生之地,绍兴市自然也是新乡贤队伍建设的先行之地,已经成为全国乡贤文化之乡和新乡贤队伍建设的标杆。绍兴市的新乡贤队伍建设,肇始于2001年上虞乡贤研究会的成立,在2015年的乡贤政策年臻于高峰。经过多年培育和发展,定位为"村民自治的有益补充"、起"补位和辅助作用"的近2万新乡贤队伍,在乡村经济、文化、公益、自治等方面发挥着积极作用,但与此同时也显现了新乡贤队伍建设流于形式、结构相对失衡,以及党政介入过度、党政机构与新乡贤组织职责和权力边界不清晰等问题。解剖这一领先全国的典型个案,对于其他地区的新乡贤队伍建设和现代乡村振兴,无疑具有较好的理论意义和现实价值。     

退化草原恢复中草原植物群落特征的变化

【目的】分析实施禁牧和草畜平衡后的退化草原植被群落特征,研究退化草原生态环境恢复情况,为乌鲁木齐市退化草地的恢复重建提供科学指导。【方法】选取乌鲁木齐市实施禁牧和草畜平衡的天然草地为对象,对不同恢复年限禁牧区和草畜平衡区的植被长势变化及植物群落平均高度、盖度和地上生物量等进行实地调查和分析,研究退化草地在恢复过程中植物群落特征的变化。【结果】(1)实施草原补奖政策后,恢复5 a后较恢复1 a,恢复8 a较恢复5 a草原植物长势明显变好。(2)禁牧区不同草地类型的植被盖度、高度和生物量随恢复时间的延长呈上升趋势,草畜平衡区不同草地类呈现先升高后降低的趋势,在恢复8 a时出现下降趋势,这可能与2018年乌鲁木齐市降雨量较低有关。【结论】通过实施禁牧和草畜平衡,乌鲁木齐市草地退化的现象得到了一定程度的遏制和改善,在政策实施8 a后草地植被恢复较好,但不同草地类型的变化有所差异,需继续加强草地资源监测。     

Policy options for Agriculture Green Development by farmers in China

Farmers are the key agents who manage land and water. Agriculture Green Development (AGD) requires a transformation in farming from high resource consumption and environmental cost to sustainable intensification with high productivity, high resource use efficiency and low environmental risk. This paper analyzes the public policy challenge of AGD and makes the case for a location-sensitive policy mix made up of regulation, advice provision, voluntarism and targeted incentives. The public agricultural extension service in China is a key resource, but one that requires reorientation and reform with the aim of better balancing high farm productivity with environmental protection.     

Towards the sustainable intensification of agriculture—a systems approach to policy formulation

The sustainable intensification of agriculture involves providing sufficient food and other ecosystem services without going beyond the limits of the earth’s system. Here a project management approach is suggested to help guide agricultural policy to deliver these objectives. The first step is to agree measurable outcomes, integrating formal policy goals with the often much less formal and much more diverse goals of individual farmers. The second step is to assess current performance. Ideally, this will involve the use of farm-scale metrics that can feed into process models that address social and environmental domains as well as production issues that can be benchmarked and upscaled to landscape and country. Some policy goals can be delivered by supporting ad hoc interventions, while others require the redesign of the farming system. A pipeline of research, knowledge and capacity building is needed to ensure the continuous increase in farm performance. System models can help prioritise policy interventions. Formal optimization of land use is only appropriate if the policy goals are clear, and the constraints understood. In practice, the best approach may depend on the scale of action that is required, and on the amount of resource and infrastructure available to generate, implement and manage policy.

1978—2018年中国农村环境管理政策演进特征——基于206份政策文本的量化分析

基于手工搜集的1978—2018年中国政府颁布的206份农村环境管理政策文本，从政策发布年度、政策发布主体、政策发布形式、政策作用对象、政策工具及政策效力6个维度构建分析框架，运用政策文献计量和内容分析方法分析了中国农村环境管理政策的演进特征。结果表明:1978年改革开放以来，中国农村环境管理政策在数量上呈整体持续上升态势；农村环境管理政策经历了探索起步(1978—1989年)、初步形成(1990—2004年)、快速发展(2005—2013年)和全面推进(2014年以后)4个阶段的演进；政策发布主体的行政级别较高且呈现多元化特征，政策联合决策程度高，但政策之间统筹性和协调性较低；政策绝大多数以通知、意见等形式发出，缺乏权威性和规范性；政策的着力点主要在原生态保护层面，对农村人居环境整治的重视程度不够；命令控制型政策是政府最为偏好的农村环境管理政策工具，经济激励型、信息公开型和自愿参与型政策工具使用不足；政策整体效力的提升主要由政策发布数量驱动，政策反馈不足、政策措施较少和政策目标量化程度低是导致政策平均效力较低的主要原因。
